标题: 这种元件的用法
这种二极管的好像用的比较少，平时不怎么用，谁能说下具体用途和可以实现哪些电路功能

What is a Switching Diode?- o' H; |  l5 V) B# K- t6 k& f+ R
Switching diodes are a single p-n diode in a discrete package. A switching diode provides the same functionality as a switch. It has high resistance below the specified applied voltage similar to an open switch, whereas above that voltage it changes in a sudden way to the low resistance of a closed switch. Switching diodes are used in devices such as ring modulation.

Applications for Switching Diodes:. d* L+ P) T% p
The switching diode is the most basic function of almost every electronic application. Switching diodes are also used in high-speed rectifying applications, such as in radiofrequency receivers. Applications also include high-speed switching, general-purpose switching and reverse polarity protection in the consumer, automotive, and telecommunication industry.

我的理解是跟普通二极管一样，只是反向恢复时间较短，是这样吗？你的英文好像是达到一定电压导通，否则，不导通。可是二极管正向也就0.7V左右啊

Switching diodes have lower power ratings than rectifier diodes, but can function better in high frequency application and in clipping and clamping operations that deal with short-duration pulse waveforms;  _7 M8 c$ I' _( Z$ M) B4 U
